Hi, I'd like to "rudely" interject here.<div><br></div><div>In our use of QGIS (multiple versions) I have found there are some UI elements which will unknowingly cause QGIS to crash on certain machines (Mac and Windows).</div>
<div><br></div><div>On some machines using a contextual element to perform a task will cause a crash, while using a "button" element or perhaps a "menu" element will not cause a crash, vice a vice versa in some instances.</div>
<div><br></div><div>It may help your 'cause to be extremely detailed in all your steps with exact use of the UI (if only for your own well being) to narrow what it is causing the crashes.</div><div><br></div><div>For instance </div>
<div>(only in my case, not suggesting it is yours I am using this as an example)</div><div><br></div><div>I found that "double Clicking" a Layer to invoke the "Layer Properties" window would cause QGIS to crash when I clicked the "Apply" or "OK" button in the "Layer Properties" window.</div>
<div><br></div><div>However, if I Control/Clicked the "Layer" and selected "Properties" everything would be fine.</div><div><br></div><div>This meant having to adjust how i interacted with QGIS UI, and took me forever to solve the issue as it was seemingly random, until I took notice of my very exact steps.</div>
<div><br></div><div>I am sorry that you are having these problems, there are fewer things as frustrating as having software crash with no apparent reason when you depend on it.</div><div><br></div><div>Good luck in your debugging hunt!</div>

<div>Hi,</div>
<div>Today I reached the same problem. In the middelof a lecture with 25 students 3 sessions crashed with no warnings.</div>
<div>I had the same lecture last week with no problems...</div>
<div> </div>
<div>I tried to work with the data myself for 1 hour. 2 times it crashed again, but without a significant reason.</div>
<div> </div>
<div>We have been using WMS-layer and shape layer.</div>
<div>A the first pc, it started with polygons didn´t appear after filling out the attributes.</div>
<div>Trying to save - a crash.</div>
<div> </div>
<div>At the second pc : While digitizing and editing. After moving an object and then digitizing it was impossible to save the layer.</div>
<div> </div>
<div>We use Snapping Options to Vertex and Segments. This we didn´t use last week at the first lessons.</div>
<div> </div>
<div>Hope anyone can help.</div>

Hi Giovanni<br>I think you already did more than enough to try to help determine what is wrong with (my) QGIS. If Im the only one getting these crashes then its safe to assume that there's something wrong "on my end".<br>
<br>I keep getting them in two machines and I have made numerous attempts to understand what the hell is wrong with this. Maybe it is some specific configuration parameter of QGIS, I dont know.<br><br>Fortunately for me there are other FOSS softwares I can use to do what I need and If I ever get rid of these crashes and find out what was causing them I will make sure to tell you.<br>
<br>Thanks again for help and efforts<br><br>Cheers<br><br><br><br><br></div>
